Harry Bosch, an LAPD homicide detective, stands trial for the fatal shooting of a serial murder suspect. A cold case involving the remains of a missing boy forces Bosch to confront his past. As daring recruit Julia Brasher catches his eye and departmental politics heat up, Bosch will pursue justice at all costs.

'Bosch' is lauded for its strong character development, especially Titus Welliver's portrayal of Harry Bosch, and realistic police work depiction. The series is appreciated for compelling storylines and high production values. However, some find it predictable and formulaic. Mixed feedback exists for later seasons, particularly Season 7, criticized for pacing, contrived plots, and political elements. The acting of supporting characters, such as Maddie Bosch, has also drawn varied responses.
